"Some Crude Production Restarts As Cool Weather Saps Canadian Wildfire"

"CALGARY, Alberta -- Some crude producers restarted operations on Tuesday in Canada's energy heartland as a mass evacuation of the Fort McMurray oil town entered its fourth week, though cool weather and light winds were helping firefighters dampen the blaze.

No oil facilities or communities were in the fire's path as of Tuesday morning as its footprint grew slightly to 523,000 hectares (2,008 square miles) from roughly 522,900 hectares on Monday, Alberta officials said at a news conference.

The blaze was spreading mainly across forested areas to the east on Tuesday as firefighters were working to hold fire breaks around prized oil sands facilities where crews have stripped away tinder-dry trees and vegetation."
